Title: The Manufacture and Production of New Colouring Matters from Diphenylamine Compounds
Inventor: JOHNSON JAMES YATE
Filed: 1906-11-16
Granted: 1907-02-14
Abstract: 25,977. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Nov. 16. Nitro- and nitrochlordiphenylamine disulphonic acids.-The 1:2:4 and 1:4:2 nitrochlorbenzene sulphonic acids are combined with metanilic acid, yielding nitrodiphenylamine disulphonic acid. In an example, the sodium salt of o-nitrochlorbenzene sulphonic acid is heated in an autoclave with metanilic acid, soda, and water ; on cooling, filtering, and pressing, the disodium salt of 2-nitrodiphenylamine-4: 3'-disulphonic acid is obtained. The product from the p-nitrochlorbenzene sulphonic acid is obtained similarly ; substitution products of the nitrobenzene sulphonic acids may be used, or, say, o-toluidine-p-sulphonic acid. In another example, 2: 6-dinitrochlorbenzene-4-sulphonic acid is dissolved in water, and a solution of metanilic acid and sodium acetate is added ; after boiling, the dinitrodiphenylamine disulphonic acid is salted out by means of potassium chloride. Isomers of the dinitrochlorbenzenesulphonic acid may be used, or derivatives of metanilic acid, such as o-toluidine-p-sulphonic acid or 1-chlor-2-aminobenzene-4-sulphonic acid. Specification No. 25,901, A.D. 1904, is referred to. Dyes, artificial.-The diphenylamine derivatives prepared as above are condensed with alkylated diaminobenzhydrols, yielding leuco bodies which upon oxidation give green dyes. In an example, the disodium salt, prepared as in the first example above, is stirred together with tetramethyldiaminobenzhydrol into monohydrated sulphuric acid ; the mixture is poured on ice and diluted with water ; upon stirring with soda the leuco body separates out and is filtered off, pressed, and dried. It is dissolved in water with soda, cooled by ice, and oxidized by manganese dioxide and sulphuric acid ; the dye is salted out and filtered &c. Other oxidizing-agents, such as bichromates, may be used. In another example, the di-potassium salt of 2: 6-dinitrodiphenylamine-4:3<1>-disulthonio acid is condensed with tetramethyldiaminobenzhydrol in presence of sulphuric acid, and the leuco body is oxidized by manganese dioxide and sulphuric acid. This dye gives a green solution in water, which becomes yellow on addition of mineral acids ; the solution in strong sulphuric acid is also yellow.

Abstract: 20,676. Conrad, r. Sept. 20, 1906, [date applied for under Patents Act, 1901]. Signalling systems; electric railways and tramways, signalling on.-A relay operated by alternating current is used in an electric railway signal system in which the track rails carry the signal and power currents. Its core has polar projections of different lengths, two of which carry closed coils to prevent the switch arm from moving when the current supplied is below a certain frequency. The coils 6, Fig. 1, are placed on the U-shaped core 1 provided with long projections 2, 5 and short projections 3, 4. The pivoted armature 10 has a flexible switch arm 11, adapted to engage a contact 12, and normally held in its off position by a spring 13. When currents of less than a predetermined frequency pass round the core 1, the closed coils 8, 9 on the projections 2, 5 exert a slight choking effect on the flux and the armature 10 remains unmoved. Above the predetermined frequency the coils 8, 9 cause a greater part of the flux to traverse the short projections 3, 4, and the armature will then be rotated to close the switch. The switch may complete the circuit of a single device, and the current for the relay is supplied to the track rails at a higher frequency that the power current from a transformer connected to an independent source. In a modified form of relay shown in Fig. 3, the core is rectangular and the exciting-winding 25 is carried on a projection 24. The closed coil 28 is carried on a projection 26 adjacent to a smaller one 27.
